IMPROVEMENT IN MACHINES FOR CUTTING OUT COLLARS.

To all whom it may concern:

Be it known that I, Gnonen K. SNOW, of Watertown, in the county ofMiddlesex and State of Massachusetts, have invented certain new anduseful Improvements in Machines for Cutting Out Collars, of which thefollowing is a specification:

My invention relates to the form and arrangement of dies by which astrip of material having two straight and parallel edges is divided intotwo or more strips by a line or lines of out other than a straight line,in accordance with the conditions described in another application for apatent of even date with this, by which an important saving in materialis effected; and it consists, first, in the use of a pair of dies orcutters, the cutting-edges of which are so formed and of such a lengththat when brought together With a piece of paper between them they willcut a slit therein of a suitable length and shape to form one-half ofthe top or bottom of a collar, said cuts being at such an angle to theedge of the strip as to give the desired width to the end and middle ofa collar, and beingrepeatedat intervals equal to the length of a collar,leaving a space between each two cuts of nearly equal length to the cutmade, to be separated by another pair of cutters made of the reverseshape, or by the same cutters, by turning the paper over and passing itthrough the machine the second time. It also consists in making theunder face of one of said cutters curved upward at either in combinationwith a means of limiting the downward movement of the movable cutter, sothat the same dies may be used to cut for all lengths of collars. Itfurther consists in so securing'the dies in the machine that the angleof their cutting-edges may be readily and easily changed with relationto the edges of the strip of paper, so as to cut a variety of styles ofcollars with the same dies or cutters. It further consists in the use,in combination With dies or cutters for cutting collars, of a punch anddie for making a register-hole for adjusting the paper properly to thecutters in the succeeding operations. It also consists in shaping theseparating-dies so that the line of cut made thereby shall cross theline of the cuts next before and next after it at their points ofjunction, for the purpose of insuring the complete severing of theparts.

It also consists in the combination of two pairs of dies or cutters,arranged to cut curved slits the reverse counterparts of each other andparts of the same dividing-line, said dies being locateda distance apartcorresponding to the length of the collars, and arranged to work inunison with each other, and made adjustable to or from each other. Italso consists in the arrangement of a single or double series of saidcutters side by side, so that a Web of material fed endwise thereto maybe cut into strips from which collars may be formed, as will bedescribed.

Figure 1 of the drawing represents a plan ofa portion of a strip ofpaper of suitable width for two collars, and showing the line of cutsfor dividing the same into two. Fig. 2 is a front elevation of ahand-machine illustrating my invention. Fig. 3 is a section on line 00 xon Fig. 2. Fig. 4 is a front elevation of'a modiiication, showing twopairs of cutters arranged to be operated in unison. Fig. 5 is ahorizontal section on line 2 2 on Fig. 4; and

Fig. 6 is a transverse section of the cutting,

dies, showing the dies for punching the register-holes. Fig. 7 is a planof a series of the severing-dies, arranged to cut a web of the materialinto strips of the proper width and shape to form collars by cutting outthe stock between the contiguous ends of two collars.

A is the lower or bed-cutter, the cuttingedge of which is curved to theshape it is desired to give to the top or bottom of the collar, and of alength a little in excess of half the length of the longest collar, saiddie being secured to the bed B of the machine by means of a circularhub, to, projecting downward from the center thereof, and titted to asuitable socket in the bed B, and secured therein by the set-screw O. Dis the upper or movable cutter, shaped to fit the cutter A, and providedWith a hub, b, by which it is attached to the plunger or cross-head E ofthe machine, where it is secured by the set-screw c. This mode ofsecuring the cutters to the bed and cross-head is adopted to enable themto be adjusted to any desired angle to the line of feed for the purposeof-- varying the style of the collarto be produced. An arm, d, issecured to the hub to of the cutter A, and projecting therefrom in ahorizontal position alongside of the cutting-edge of the die A carriesat its end and near the ,end of punch e, which works in unison with thefemale die f formed in the cutter D, to punch the register-holes, asshown at g, Fig. 1.

is aspring, secured to the bed near the punch e, to lift the paper offfrom said punch after the registerhole is punched. An adjustableregister-pin, z, is secured to the bed of the ma chine to determine thelength of the paper to be fed at. each movement of the cross-head. G isa cam-lever, by means of which the upper cutter is operated, and h is anadjustable stop to limit the movement of said lever, and, consequently,the depth to which the upper die can descend and the length of slit cutthereby, the lower face of the upper die D being curved upward at eitherend for that purpose, as shown in Fig. 2. H is a shaft, upon which ismounted the roll of paper to be divided, the paper being guided underthe cutter by the grooves j j, which effectually prevent the paper frombeing lifted by the upward movement of the upper cutter.

The paper or other material is fed to the die by hand, the hole formedby the punching-dies being placed over the register-pin i to determinethe position, when the cam-lever G is thrown back so as to depress theupper cutter and cut a curved slit through the material, as shownfrom kto l in Fig. 1. The paper is then moved forward again a distance equalto the length of the collar to be cut, the distance between the punch eand the register-pin i being at all times adjusted to the length of thecollar it is intended to produce. As the cuttingdie is but a littlelonger than one-half of the longest collar, it is evident that if thematerial is moved a distance equal to the length of a collar that whenthe material has passed through the machine it will not be divided, butwill have a series of curved slits cut through the same, a portion ofthe material between each pair of said slits nearly equal to halt thelength of the collar remaining uncut. To complete the division with asingle pair of cutters the strip of material is turned the other sideup, and passed through the machine a second time the cutters acting uponthe uncut portions, the cuts thus formed being curved in the reversedirection to those previously made, and slightly crossing the same atthe points of intersection, as shown at 70, Z, and m, Fig. 1.

A complete division of the strip may be accomplished by one passagethrough the machine by using two cutting-dies, arranged to cut curvedlines the reverse of each other, the distance between said cutters fromcenter to center being equal to one and a half times the length of acollar, said cutters bein g so arranged that they may both be operatedby one movement, as shown in Figs. 4 and 5. When two pairs of cuttersare used they must be arranged so that they may be adjusted withrelation to each other in order to adapt them to cut differeni;i1l5engths of collars, as shown in Figs. 4 an the die A, the

After the material has been prepared, as described, in strips having onestraight edge and one edge out into a series of double reversed curves,as shown in Fig. 1, said strips of material are fed under another pairof dies, (not shown in the drawing,) by which the ends of the collarsare shaped by cutting out a piece of waste, as shown by dotted lines atM in Fig. 1. v

When it is desired to cut a shorter collar 'the stop'screw h is turnedout so as to shorten the movement of the lever G, and, consequently,reduce the depth to which the upper cutter will descend by virtue of thecurved under surface of said cutter, shorten the slit which will be cutthereby; and, if the two pairs of cutters are used, they must beadjusted in relation to each other. The register-pin i must also beadjusted in relation to the registerpunch a to adapt the machine todifferent lengths of collars.

It is evident that the cross-head may be operated by power, and thestrip of material may be fed to the dies automatically, and thestitching and line of fold may be embossed thereon and the button-holesbut therein at the same time that the cutting is performed, if desired.

A seriesof the cutters above described may be arranged on a singlecross-head in such a manner that a number of strips may be cut at thesame time from a web or roll of collar material, a pair of rotarycutters being used between each pair of shear-cutters so as to form thestraight edge of the strips; or the rotary cutters may be dispensed withand a continuous series of curved cuts be formed, a sufficient number ofthe curved shear-d being used to cut a web of collar material endwise tosaid dies into strips having two curved edges of suitable shape to formthe top and bottom edges of a collar.

By virtue of the peculiar shape of the cut made at each movement of thedies, and the relation of the first to the second out, the lines of thetwo cuts will cross each other at their intersection just enough toinsure a complete separation of the material, the extent of saidcrossing being limited by the adjustment of the vertical movement of thedie.

It will be seen by reference to Fig. 1, that the collar made will have aprojecting point in the center of the 'top or bottom edge at m, whichpoint, of necessity, varies with thevariations in the length of thecollar, it being somewhat larger in the longest collars, and almostentirely disappearing when the shortest collars are cut, owing to thefact that the curved edge of all the different sizes of collars are cutby the same cutters, the different lengths being obtained by varying thevertical movement of the movable die and the feed of the material, and,in case of the use of two sets of cutters, in adjusting said cutterstoward or from each other. This projecting point or ear, in the centerof the longer collars, is cut from what otherwise would be waste, andenables me to make equally as serviceable a collar from less materialthan heretofore, for

the reason that, when said point is on the bottom of the collar, itserves to strengthen the button-hole while the band on either sidethereof may be made narrower than usual, so that two series of collarsmay be cut from a narrower strip of material than could be done if saidprojection were not used. When the.

bottom of the collar is made straight, and the top curved, theprojecting point or car will be in the center of the top or turn-overportion of the collar, and serves to cover the center button-hole, eventhough the sides of the turnover portion be quite narrow.

What I claim as new, and desire to secure by Letters Patent of theUnited States, 1s-

l. The cutting-dies A and D arranged and applied to the bed andcross-head as herein set forth, so that the angle of the cut may bereadily and easily adjusted to change the shape of the collar,substantially as described.

2. A pair of dies for separating paper or other material by a singleline of out, the cutting edge of one or both of which is so formed atits ends that the length of cut made thereby may be varied by varyingthe travel of the moveable, die, substantially as described.

3. In combination with a pair of cutters, one or both of which has itscutting-face curved, so that the length of the cut made thereby may bevaried by varyingthe travel of the movable die, I claim an adjustablestop to limit the movement of the movable die, substantially asdescribed.

erating as herein set forth, for the purpose of dividing a strip ofpaper or other material longitudinally into two equal and similar partsby a series of successive cuts, when said dies are so shaped that theline of each successive cut shall slightly cross the line of the outimmediately preceding it, substantially as described, for the purposespecified.

8. The arrangement of two series of cuttingdies working in unison, oneof said series being located in advance of the other, and the reversecounterparts thereof in form, so that a web of material fed endwisethereto, and acted upon thereby, will be cut into a series of strips,one or both edges of which are curved, substantially as described.
